Description

Technical Field

[0001] This utility model relates to the technical field of navigation marks, and in particular to a rod-type floating navigation mark for inland waterways. Background Technology

[0002] As a crucial navigational aid in inland waterways, floating buoys primarily function to float on the water's surface, reflecting channel dimensions, determining channel direction, and marking channel boundaries, thereby ensuring the safe navigation of vessels.

[0003] Existing floating navigation aids typically consist of a buoy, chassis, support base, rod-shaped light frame, and a buoy light mounted on the light frame. They utilize built-in circuitry within the buoy and chassis to control navigation lights and other indicators on the light frame, thus providing auxiliary guidance for ship navigation at night. Currently, existing buoy lights can emit light of the prescribed color and flashing frequency at night, achieving the specified illumination angle and visibility distance.

[0004] However, due to its relatively traditional design, the buoy light is fixedly installed on the support base without any moving mechanism, resulting in poor visibility when observed at a distance. It is difficult for distant vessels to clearly identify it, which in turn affects its ability to indicate the direction of navigation and fails to fully meet the needs of efficient navigation assistance in inland waterways.

[0005] In view of this, the inventor has designed a rod-type floating navigation mark for inland waterways, which leads to this invention. Utility Model Content

[0006] To solve the above problems, the technical solution of this utility model is as follows:

[0007] A rod-type floating buoy for inland waterways includes, from bottom to top, a buoy, a base, a support, a rod-type light frame, and a buoy light mounted on the light frame. The light frame has a swing shaft at its bottom. The support has a vertically penetrating mounting groove. The mounting groove has a rotatable spherical connecting structure. The swing shaft is fixed to the spherical connecting structure and its axial direction passes through the center of the spherical connecting structure. The top opening of the mounting groove forms a limiting edge around the swing shaft to limit its swing range.

[0008] Preferably, the sidewall in the middle of the mounting groove is recessed inward to form a limiting cavity with an arc surface, and the arc surface of the limiting cavity is fully fitted with the spherical connecting structure to form a rotational fit.

[0009] Preferably, the spherical connecting part is obtained by transversely cutting two parallel planes symmetrically distributed about the center of the same sphere, retaining the portion between the two parallel planes. The upper and lower sides of the spherical connecting part form flat cut surfaces accordingly, and the swing shaft passes through the center of the two cut surfaces and is fixed at the center position of the spherical connecting part.

[0010] Preferably, a cylindrical angle limiting cavity is formed on the upper side of the limiting cavity, and an annular flexible contact pad is embedded in the inner wall of the angle limiting cavity. A relief groove for the swing shaft to pass through is formed through the middle of the flexible contact pad.

[0011] Preferably, the clearance groove includes a vertical section on the upper side and an inclined section on the lower side of the vertical section, the inclined section extending obliquely along the edge of the vertical section to the edge of the limiting cavity.

[0012] Preferably, a connecting groove is formed through the upper side of the chassis, connecting the mounting groove and the internal cavity of the chassis, and an annular mounting ring seat is formed at the inner top of the internal cavity of the chassis and around the connecting groove.

[0013] Preferably, it further includes a spring-loaded mechanism, which includes a connecting sleeve threaded to and sleeved at the end of the swing shaft, a plurality of positioning shafts fixedly inserted on the mounting ring seat, and a plurality of return springs disposed between the positioning shafts and the connecting sleeve at corresponding positions. One end of the return spring movably contacts the periphery of the connecting sleeve and the other end is sleeved on the outside of the positioning shaft. The middle part of the positioning shaft is provided with a limiting edge for movably contacting and stopping the return spring.

[0014] Preferably, the connecting sleeve is recessed inward to form a plurality of positioning grooves that are one-to-one with the positioning shaft. The bottom of the positioning groove is provided with positioning posts that are coaxially distributed with the positioning shaft. One end of the reset spring is sleeved on the outer periphery of the positioning post and movably contacts the bottom of the positioning groove.

[0015] Preferably, the mounting ring seat has a plurality of positioning holes extending radially through it, and one end of the plurality of positioning shafts is threaded into the positioning holes.

[0016] Preferably, the positioning holes are evenly distributed around the mounting ring seat and there are 12 of them, and the positioning shaft and the return spring are correspondingly provided in 12 locations.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention utilizes a spherical connecting structure that rotates within the mounting groove, and fixes the bottom of the light frame to the spherical connecting structure via a swing shaft. The periphery of the opening at the top of the mounting groove forms a limiting edge for the swing range of the swing shaft, allowing the entire rod-shaped light frame to swing within a certain conical space centered on the center of the spherical connecting structure. Combined with the undulations of the water surface, this causes the buoy to rise and fall, thereby driving the light frame to swing back and forth within a limited space. This results in irregular movement trajectories for the buoy lights on the light frame, significantly improving their visibility and indication effect, and fully meeting the needs of efficient navigation in inland waterways.

[0019] This invention utilizes water waves to cause the light frame to swing irregularly within a conical space, creating a dynamic trajectory for the buoy light. This breaks through the traditional fixed mode and significantly improves its visibility at long distances.

[0020] In addition, the combination of the spherical connection structure and the limiting structure allows for flexible swinging, while the swing range is controlled by the limiting edge and the rebound mechanism to avoid structural damage caused by excessive shaking.

[0021] Notably, this solution requires no additional power, utilizing natural waves to achieve the swaying of the light fixture, making it energy-efficient, environmentally friendly, and adaptable to inland waterway environments. Attached Figure Description

[0033] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0034] Please see Figures 1 to 7 This is a rod-type floating navigation mark for inland waterways, which is the preferred embodiment of the present utility model. It includes a buoy 100, a base 200, a support 300, a rod-type light frame 400, and a buoy light 500 mounted on the light frame 400, arranged sequentially from bottom to top.

[0035] in:

[0036] The buoy 100 is hemispherical and has a sealed cavity inside to provide buoyancy under the water surface, allowing the entire device to float on the water surface. The bottom of the buoy 100 is generally equipped with a fixing ring 110, which facilitates the connection of it to a fixed point or to an adjacent floating buoy by means of a corresponding fixing rope, so as to fix its position on the inland waterway and thus realize the stable indication function of the entire floating buoy.

[0037] The chassis 200 is fixed to the upper side of the pontoon 100 and has an internal cavity (not shown in the figure). The cavity typically houses corresponding circuitry (not shown in the figure). For power supply, inclined solar photovoltaic panels 210 are generally installed around the perimeter of the chassis 200 to provide a stable power supply to the internal circuitry and the buoy lights 500 on the light stand 400, ensuring their operation at night. Furthermore, the upper surface of the chassis 200 typically has an antenna device 220, electrically connected to the circuitry, for communication with the outside world, facilitating remote status monitoring and functional operation.

[0038] The support base 300 is locked and fixed to the upper center of the chassis 200 to provide a stable connection base and achieve a stable connection with the rod lamp holder 400.

[0039] The rod-shaped lamp holder 400 is mounted on the support base 300. The wiring harness 230 of the circuit device passes through the axial center of the lamp holder 400 and is finally electrically connected to the buoy lamp 500 installed at the top of the lamp holder 400, thereby realizing the control of the buoy lamp 500.

[0040] The above describes the general structure of a floating navigation beacon. The improvements in this embodiment are described in detail below:

[0041] First, an upper wiring cavity 410 is provided inside the lamp holder 400. A fixing hole 411 is provided at the bottom of the upper wiring cavity 410. A rod-shaped swing shaft 420 is threaded onto the fixing hole 411. The swing shaft 420 is coaxially distributed with the lamp holder 400 and a lower wiring cavity 421 is formed inside it, which is distributed along its axial direction and connects to the upper wiring cavity 410. The lower wiring cavity 421 extends through to the bottom end of the swing shaft 420. Thus, through the upper wiring cavity 410 and the lower wiring cavity 421, the wire harness 230 used to connect the circuit device and the buoy lamp 500 can be easily introduced to achieve internal wiring, which does not affect the swing of the lamp holder 400 and can also achieve smooth wiring.

[0042] A mounting groove 310 is vertically through the support base 300. The mounting groove 310 includes an upper cylindrical angle limiting cavity 311 and a lower limiting cavity 312. The limiting cavity 312 protrudes outward and is recessed to form a spherical cavity structure with an arc surface. A spherical connecting part 600 is movably embedded in the limiting cavity 312. The spherical connecting part 600 is obtained by transversely cutting two parallel planes symmetrically distributed about the center of the same sphere, retaining the portion between the two parallel planes. The upper and lower sides of the spherical connecting part 600... The sides form flat cross-sections (not shown in the figure). The swing shaft 420 passes through the center of the two cross-sections and is fixed at the center of the spherical connecting part 600 (i.e., through its center). The spherical surface of the spherical connecting part 600 and the arc surface of the limiting cavity 312 are completely fitted to form a movable connection state that can rotate relative to each other. Thus, through the rotational connection between the spherical connecting part 600 and the limiting cavity 312, the entire lamp holder 400 can swing relative to the support base 300, thus realizing the motion basis of the buoy lamp 500.

[0043] Furthermore, the peripheral edge of the top opening of the angle limiting cavity 311 forms a limiting edge (not shown in the figure) for limiting the swing range of the swing shaft 420. By setting the limiting edge, structural damage caused by excessive shaking of the lamp holder 400 can be avoided.

[0044] Preferably, an annular flexible contact pad 700 is embedded in the inner wall of the angle limiting cavity 311. The center of the flexible contact pad 700 forms a relief groove 710 through which the swing shaft 420 passes. In this embodiment, the limiting edge is specifically formed at the top edge of the relief groove 710 of the flexible contact pad 700, and the flexible contact pad 700 is a silicone pad. Thus, the flexible contact pad 700 can buffer the impact force when the lamp holder 400 contacts the limiting edge, forming a flexible contact and preventing the lamp holder 400 from wearing out too quickly.

[0045] Furthermore, the clearance groove 710 includes a vertical section 711 located on the upper side and an inclined section 712 located on the lower side of the vertical section 711, the inclined section 712 extending obliquely along the edge of the vertical section 711 to the edge of the limiting cavity 312.

[0046] Preferably, a cavity (not shown in the figure) is formed inside the chassis 200, and a connecting groove 240 that connects to the mounting groove 310 is formed through the upper side of the cavity. An annular mounting ring seat 250 is integrally formed by protruding downward from the inner top of the cavity inside the chassis 200 and around the connecting groove 240.

[0047] Specifically, this embodiment also includes a spring-loaded mechanism 800, which includes a connecting sleeve 810 threadedly connected to and sleeved at the end of the swing shaft 420, a plurality of positioning shafts 820 fixedly inserted on the mounting ring seat 250, and a plurality of return springs 830 disposed between the positioning shafts 820 and the connecting sleeve 810 at corresponding positions. One end of the return spring 830 movably contacts the periphery of the connecting sleeve 810 and the other end is sleeved on the outside of the positioning shaft 820. The middle part of the positioning shaft 820 is provided with an annular limiting edge 821 for movably contacting and stopping the return spring 830.

[0048] Thus, the combination of the spherical connection structure with the limiting edge and the spring mechanism 800 allows the lamp holder 400 to swing flexibly, while the limiting edge and the spring mechanism 800 control the swing range, preventing the lamp holder 400 from being damaged too quickly due to excessive shaking.

[0049] Furthermore, the connecting sleeve 810 is recessed inward to form several positioning grooves 811 that are one-to-one with the positioning shaft 820. The bottom of the positioning groove 811 is provided with positioning posts 812 that are coaxially distributed with the positioning shaft 820. One end of the return spring 830 is sleeved on the outer periphery of the positioning post 812 and movably contacts the bottom of the positioning groove 811.

[0050] Thus, the positioning groove 811 and positioning post 812 can stably limit the end of the return spring 830, so that it can maintain a stable connection between the connecting sleeve 810 and the positioning shaft 820 during the swinging process of following the swing shaft 420. This allows the swing shaft 420 to always receive the elastic force applied by each return spring 830, giving it an elastic tendency to stay in the center position.

[0051] In particular, in order to achieve the swing of the lamp holder 400 while maintaining its elastic centering tendency, the selection of the elastic coefficient of the return spring 830 is especially important. That is, a spring with an excessively large elastic coefficient cannot be selected, which would make the centering tendency of the lamp holder 400 too strong, producing an effect similar to being fixed on the support 300. Therefore, a return spring 830 with a suitable elastic coefficient range needs to be selected to achieve the above process.

[0052] Preferably, the mounting ring seat 250 has a plurality of positioning holes 251 extending radially through it, and the outer periphery of a plurality of positioning shafts 820 is provided with threads. The end of the positioning shaft 820 away from the return spring 830 along the limiting edge 821 is threaded into the positioning hole 251. In this embodiment, the positioning holes 251 are evenly distributed around the mounting ring seat 250 and there are 12 of them. The positioning shafts 820 and the return spring 830 are provided accordingly.

[0053] like Figure 6 , 7 As shown, in this embodiment, limited by the limiting edge and the spring mechanism 800, the swing range of the lamp holder 400 is a range of 5° to each of its circumferential sides, and this range can be achieved within a conical area, and is not limited to a specific cross-section.

[0054] The beneficial effects of this utility model are as follows:

[0055] This invention utilizes a spherical connecting structure rotatably installed within the mounting groove 310, and fixes the bottom of the lamp holder 400 to the spherical connecting structure via a swing shaft 420. The periphery of the top opening of the mounting groove 310 forms a limiting edge for the swing range of the swing shaft 420, allowing the entire rod-shaped lamp holder 400 to swing within a certain conical space centered on the center of the spherical connecting structure. Combined with the undulations of the water surface, the buoy 100 rises and falls, thereby causing the lamp holder 400 to swing back and forth within a limited space. This results in the buoy light 500 on the lamp holder 400 generating irregular movement trajectories, significantly improving its visibility and indication effect, and fully meeting the needs of efficient navigation in inland waterways.

[0056] This invention utilizes water waves to cause the light holder 400 to swing irregularly within a conical space, enabling the buoy light 500 to generate a dynamic trajectory, breaking through the traditional fixed mode and significantly improving long-distance visibility.

[0057] In addition, the combination of the spherical connection structure and the limiting structure allows for flexible swinging, while the swing range is controlled by the limiting edge and the spring mechanism 800 to avoid structural damage caused by excessive shaking.

[0058] Notably, this solution requires no additional power, utilizing natural waves to achieve a 400-degree swing of the light fixture, making it energy-efficient, environmentally friendly, and adaptable to inland waterway environments.

[0059] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
